// This class is created to manage the specification of the 
// function to be plotted through a dialog interface. 
// 
// When the interface is displayed by calling exec():
//
// The current value of the data member fxText is used to 
// set the contents of the QLineEdit in the dialog window.
// 
// When the interface OK button is hit:
//
// The program validates the input
//
//     -if the input is acceptable, the data member fxText is set
//      to the contents of the QLineEdit in the dialog window. The
//      dialog interface is closed. 
//
//     -if the input is unacceptable,an error message box is displayed
//      the dialog is not closed and the fxText is not altered.
//
// When the interface Cancel button is hit:
//
//     -the dialog interface is closed and the 
//      the value of the fxText data member is not changed.
